WINDOW SASI-I.

I Application filed January 18, 1923. Serial No. 613,468. I

To all whom it may concern:

Be it known that we, HANS S'rAUeAAnD and (honor WA'r'rs, itizens of the United States, and residents of Detroit, v ayne County, Michigan, have invented anew and Improved Window Sash, of which the following is a specification.

This invention relates to the construction of vertically slidable window sashes and the casings therefor, and its object is to provide a window construction of this character wherein the sashes may be swunginward on a horizontalaxisfrom vertical to horizontal position so that the outside surfaces of the panes of said-windows may be conveniently cleaned. y r

This invention consists in a window cas' ing having vertical grooves in. its opposed upright side members, a vertically slidable sash having grooves in alinement with the grooves in the casing "and having pins'at its lower end extending across the grooves in the sash into the grooves in the casing, a laterally movable guide bar in each groove in the sash and adaptedto be moved into and out; of the groove in the casing and having a hole atits lower endtoreceive the adjacent pin on the sash by which the guide bar is prevented from moving longitudinally relative to the sash, the

guide bars having longitudinal grooves to receive the sash cords which attach 'tothe pins at the lower ends of these guide bars.

It also consists in a vertically .movable rod in each groove in the sashandguides therefor preventing lateral movement of the rod, and toggle links connecting: the rod and out of or into the groove in the'casing;

It also consists in a leaf spring attached to the casing at the bottom of each groove therein and near its lower end so that the spring may extend into the path of theadjacent pin on the sash, the spring being normally held out of this path by the ad jacent guide bar, the spring-serving,when the guide bar is withdrawn from the groove in the casing-to permit the window to be swungto horizontal position, to prevent the In the accompanying drawings, Fig. l is a section of our-improved, window sash in a plane parallel to the glass therein and at the surfacethereof. Figs. 2 to 6 inclusive are sections on the lines 22, 33, 44, 55 and 6-6 respectively of Fig. 1.

Similar reference characters refer to like parts throughout the several views. The window sash shownin the drawings 1S generally of well known construction, having the transverse upper member 1, the transverse lower'member 2 and the vertical side members'or stiles 3. As shown in Figs. 4, 5 and 6, the outer edges of these stiles 3 are grooved to receive the metal'shells 4, each consisting of the outerstrips 5, the parallel inner strips 6, the middle strip 7 and the edge strips 8 between the strips 5 and 6, The channel formed by the strips 6 and 7 receives the guidebar 9 which is also preferably formed of sheet metal, this guide bar consisting of the sides 10 and the grooved edge 11. This guide bar 9 is laterally slidable between the side strips 6. The ends 12 of the outer strips 5 may be folded in, as shown in Fig. 2 to lie against the transverse members of the sash.

Connected to the middle portion 7 of each 'shell'isa pin '14, shown in Fig. 6, which may be of any desired construction but we prefer to form the same with a reduced portion 15 which extends through a collar 16 seated in a proper hole in the lower end of the middle strip 7 oftheshell and is held in position by a nut 17 andany desired number of washers 18. The stile 3 is formed with a recess 19 to receive the nut and washers.

The grooved portion ll of each guide bar is formed with a hole 20 to receive the pin 14 and this guide bar is therefore prevented from moving longitudinally in thechannel formed in the metal shell 4, but it is permitted to move laterally into and out of the groove 22 in the portion 23 of the window casing-stile. This portion 23-is shown to be a separate part of the window casing, but it is to be understood that the grooves 22 may be formed inthe well known upright portion 24 of the casing. WVherenew window casings are installed in buildings the side members 24, or stiles, can be grooved, but where our improved windows are to be installed in buildings already provided with window casings, grooving of these stiles 24 may present serious difiiculties, so

that it will usually be found advantageous to secure grooved strips 23 to these upright side members of the window casings At any desired intervals along the bottom of the channel in the metal shell are secured the, clips 26, shown in section in Fig. 5, within which the operating rod 27 is vertically slidable. preferably of sheet metal, although not necessarily so, and is movable up anddown' by means of a lever 28 having down-turned edges mounted on the pivot pin 29 carried by the sides 10 of the guide bar, as shown in Fig. 1. This lever also carries a pivot pinSO extending across through the top of the operating bar 27 so that whenthis lever is swungup on thepivot29 the operating bar 2? will be lifted."

Near the lower end ofthis operating har is-a pivot pin 31' which connects-by means of the links to the pivot pin extending across between the. sides 10 of the guide bar. \Vhen the lever 28- is swung up, the operating bar 27 will he moved upward and the guide bar 9 will be moved inward out of the groove 22 in the windowcasing. The lever 28 and the links 32 constitute toggle links which move the guide bar intoand'out of the adjacent groove 22 in the window casing. Vi hen entirely out of this groove, the sash may be swung on the pin 1i asa-pivot' to horizontal position, as indicated in Fig. 3, which permits the outer side of the pane to be cleaned.

The sash cord 3-? extends over the usual roller and connects to tlie'usual weight, but such mechanismis omitted as it is well known in this-art; A: metal strip is formed into a loop 39 which receivesthe reduced portioniOot the pin 14: at its lower end and has its upper end 42. secured to the sash cord, so that the sash weight and cord can assist in raising the window and hold it in any desired" position.

When the sash is swung down to the horizontal position shown in Fig. 3, a large port-ion of tlieweight ofthe sash is taken from the sash cord-so that the sash weight is liableto raise the end' ofthe sash to which it is connected. In order to 13 1 6, vent this, we secure the upper end" of a fiat spring; 43 to the stile of the window casing atthe bottoinofthe groove 20 therein in anydesired manner, screws 44 being. shown. lVhile the guide bar 9 is in the position shown in Figs. 1, 4t, 5 and 6, the sash cords and weights operate in: the usual] manner, the spring, 43, oeing pushed back out of the path ofthe pin 14. But when the guide bar is pulled inwardxso as to release the windowsash from the casing, at which time the sash should be so low that the pin 1 is below the spring 43, this spring swingsinto thepath ofthe-pin 14L and' prevents the; lower end of the sash from being pulled up by the windowv cords. The

This rod 27. is; alsor sash and its casing may be of any desired material and wedo not wish to be limited to such articles made of'wood.

It will be understood that this construction-isiduplicatedat bothsides oi the window if desired and that the shells 4 may be omitted, if desired, the guide bars being mounted directly in grooves in the stiles of't'hesash. The-invention permits the outsides of the panes to be cleaned at any time without interfering with exterior screens. lilerely swinging the levers. 28 causes the guide bans to move in andout. hen a sash is to be removed from the casing, it islowereduntil the pins 1% are below the springs -13. The guide bars are then drawn inby swinging up the levers and" the sash is swung to horizontal. position. One of the springs l3is, then pushed back to release the adjacent pinh which permits the sash to be liited out of the casing and the sash cords to be disconnected.

The details of" construction and the proportions of the parts may. all be changed by those skilled in the art without; depart ing from the spirit of our invention asset forth in the following claims.

e claim 1; In a window, the combination of a casing having vertical grooves, a sash mounted in the casing and having grooves in its side edges, guide bars mounted in the grooves in the sash and adapted to extendinto the grooves in the casing, means to move the guide hars into and out of the grooves in the casing, pins extending from the sash, and" a leaf'spring mounted in a groove in the casing and adapted to have one end exte-nd'int-o the path of apin on the sash, said spring being moved out of said path by the adjacent guide bar when said guide bar is in operative positionin the groove in the casing,
